标准摘要
[中文适用范围]： 本 SAE 标准规定了用于测量车辆总重低于 4336 kg 的道路车辆的摩擦材料、隔音材料和盘式制动片组件的挠度的方法。 SAE J3079 的这一部分包括环境温度条件下各种压力下的挠曲和蠕变测试。该 SAE 测试方法与 SAE J2468 和 ISO 6310 的不同之处在于测量挠度时施加到测试样本的预载荷和最大载荷。它还引入了额外的测量，例如偏转偏移、滞后和蠕变。 [外文原描述]： This SAE Standard specifies a method for measuring the deflection of friction materials, noise insulators, and disc brake pad assemblies to be used in road vehicles with a Gross Vehicle Weight Rating below 4336 kg.This part of the SAE J3079 includes the test for deflection and creep at various pressures under ambient temperature conditions.This SAE test method differs from SAE J2468 and ISO 6310 in the preload and maximum load applied to the test sample when deflection is measured. It also introduces additional measurements such as for deflection offset, hysteresis, and creep.Cross Reference:
